Hmmm. The common idiom for this is:
page = double('page')
controller.stub(:render).with(:update).and_yield(page)
page.should_receive(:replace_html).with(...)
This does not seem to work with rspec-2/rails-3. Don't know why yet (won't be
able to look for a bit), but my guess is that something (like rspec :) ) is
adding render() to the controller even later than this stub does. I'll follow
up if I learn something.
HTH,
